Zayn - who was seated with Perrie's family and chatted with her mother, Debbie - screamed: "I love you, Perrie!"

A source told the Daily Mirror: "It's well and truly on. They are determined to work through this and were all over each other at the end of the show.

"The fact that Zayn is talking, and still friendly, with Perrie's family speaks volumes. It's all systems go."

The One Direction singer was accused by Courtney of having a one night stand with her last month, who claimed she was invited back to the star's £2.2 million North London home after a night out.

She said: "Zayn looked me in the eyes and said, 'You're so hot, you're so fit, you're beautiful.' We sat on his bed and before I could even say anything he started snogging my face off, kissing me passionately. It just snowballed from there. We fooled around, then had sex. It was amazing."
